Depends on what you consider "Fun" - to me, 1366 was the last of the challenging and skilled over clocking (2011 takes some skill, 1150 absolutely zero as its all multi driven) - 2011 would be the logical step up from 1366, though 1150 will hold its own and can see massive clocks depending on the chip you get.

Right now I have a X58 Sabertooth and an i7 920. Not sure how well it clocks since it's mining litecoins and PTS the day I've got it.

I'm planning on building a nice rig (with a case this time) for myself once I make some money off the coins.

So what's more fun to overclock? LGA1366, LGA1150 or LGA2011?

What boards would you recommend (that won't break the bank)?

Was in similar situation as you.....i7 920 D0 chip. OC to 4.0 ghz at 1.25 volts. upgraded 5870 to 7950. Gave new life to PC gaming.....This was late 2012. By April 2013....The upgrade bug hit me and put a big hole in my wallet and paypal account. Went with x79 RIVE w/ 3930k and dual 7970 watercooled. See sig Blowitoutyourass 2. You know that you want to pull the trigger on a Rampage Black Ed w/ 4930k.
